Whirlpool Side By Side Refrigerator Ice In Bottom Of Freezer
Ice at the bottom of your freezer is almost always caused by a clogged defrost drain tube. When the refrigerator goes through its automatic defrost cycle, the melting water cannot exit through the drain and instead pools at the bottom, where it refreezes into a solid sheet.
To fix this, you must manually clear the ice from the drain trough and flush the drain line with hot water using a turkey baster or syringe to restore proper drainage.
Finding a solid sheet of ice at the base of your freezer is a common frustration for many homeowners. You might notice water leaking onto the kitchen floor or struggle to pull out the bottom storage bin because it is frozen shut. If you are dealing with a whirlpool side by side refrigerator ice in bottom of freezer, you likely want a solution that doesn’t involve an expensive service call.
I promise that with a few basic hand tools and about an hour of your time, you can diagnose and repair this issue yourself. This is a straightforward DIY project that fits right into the wheelhouse of anyone who enjoys tinkering in the garage or maintaining their own home. We are going to look at the mechanics of the defrost system and how to clear the blockage for good.
In this guide, we will walk through the step-by-step process of removing the freezer panels and accessing the drain trough. We will also discuss the infamous “duckbill valve” that often causes these clogs in Whirlpool models. By the time we are finished, your refrigerator will be draining properly, and your kitchen floor will stay dry.
Understanding the Mechanics of Freezer Ice Buildup
To fix the problem, you first need to understand why the water is there in the first place. Modern refrigerators are “frost-free,” which means they have a defrost cycle that runs several times a day. During this cycle, a heating element turns on near the evaporator coils to melt any frost that has accumulated.
This melted frost turns into water, which is supposed to flow into a drain trough located directly beneath the coils. From there, it travels down a plastic tube to a drain pan located underneath the refrigerator near the compressor. The heat from the compressor then evaporates the water into the air.
When that drain tube becomes restricted or frozen, the water has nowhere to go. It overflows the trough and spills onto the floor of the freezer compartment. Because the freezer is still running its cooling cycle, that standing water quickly turns into a thick sheet of ice.
Solving the Whirlpool Side by Side Refrigerator Ice in Bottom of Freezer Issue
The first step in addressing a whirlpool side by side refrigerator ice in bottom of freezer is to prepare your workspace and gather the necessary tools. You don’t need a massive rolling tool chest for this job, but having the right items on hand will make the process much smoother.
You will need a 1/4-inch nut driver or a socket set, a Phillips head screwdriver, and a large towel to soak up any melting ice. I also highly recommend having a turkey baster or a large plastic syringe and a bowl of very hot (but not boiling) water. If the ice is particularly thick, a handheld hair dryer can speed up the process, but use it with extreme caution.
Before you begin any work, safety is the priority. Always unplug the refrigerator from the wall outlet. You will be working near electrical components and water, which is a dangerous combination. If your unit is built-in and hard to move, flip the breaker in your electrical panel to ensure the power is completely off.
Step 1: Clearing the Freezer Compartment
Start by removing all the food from the freezer side of the unit. Since this repair can take 30 to 60 minutes, it is a good idea to put your frozen goods into a cooler with ice packs. You will also need to remove all the shelves and the bottom storage bins.
Most Whirlpool side-by-side models have shelves that either lift up and out or have small plastic locking tabs. Take your time and don’t force them; plastic becomes brittle when cold and can snap easily. Once the freezer is empty, you will likely see the ice sheet clearly at the very bottom.
Step 2: Removing the Back Access Panel
Look at the back wall of the freezer. You will see a plastic or metal panel held in place by several hex-head screws. Use your 1/4-inch nut driver to remove these screws. Keep them in a small magnetic tray or a cup so they don’t get lost in the ice.
Carefully pull the panel forward. Be mindful that there may be wires connected to a fan motor attached to this panel. You can usually disconnect the wire harness or simply set the panel to the side if the wires are long enough. Behind this panel, you will see the evaporator coils, which look like a small car radiator.
Step 3: Melting the Ice in the Trough
Directly beneath the evaporator coils is the drain trough. If you have been seeing ice on the floor, this trough will likely be completely filled with a solid block of ice. This is the “plug” that is preventing the water from escaping during the defrost cycle.
Use your turkey baster to apply hot water directly to the ice in the trough. Do not try to chip the ice away with a screwdriver or a knife. The aluminum coils and the defrost heater are very fragile; a single puncture will ruin the entire refrigerator. Patience is your best tool here.
Deep Cleaning the Drain Line
Once the surface ice in the trough has melted, you will see a small hole in the center. This is the entrance to the drain tube. Even if the trough is clear, the tube itself is likely frozen solid several inches down. You must continue to flush the line with hot water until you hear the water draining freely into the pan below.
If the water just sits in the hole and doesn’t go down, the clog is stubborn. You can use a piece of flexible plastic tubing or a heavy-gauge weed eater string to gently probe the line. Avoid using metal wire, as it can puncture the plastic drain hose, leading to a permanent leak inside your walls or floor.
The Infamous Whirlpool Duckbill Valve
Many Whirlpool models manufactured over the last decade use a specific part at the end of the drain line called a duckbill valve. This is a rubber grommet shaped like a duck’s beak located at the very bottom of the drain tube, usually accessible from the back of the fridge.
The purpose of this valve is to let water out while preventing warm air and insects from entering the freezer. However, these valves are notorious for getting clogged with “slime” or dust, causing the lips of the valve to stick together. When this happens, the water backs up, freezes, and creates the ice sheet you see.
To fix this properly, pull the refrigerator away from the wall and remove the lower rear cover. Locate the drain tube where it exits the cabinet and enters the evaporator pan. Remove the rubber duckbill valve and wash it thoroughly with warm, soapy water. Some DIYers choose to “snipe” the tip of the valve with scissors to create a larger opening, ensuring it never sticks shut again.
Checking the Door Gaskets and Seals
While a clogged drain is the primary suspect for a whirlpool side by side refrigerator ice in bottom of freezer, you should also inspect your door seals. If the freezer door isn’t sealing tightly, warm, moist air from the kitchen enters the compartment constantly.
This moisture condenses on the coils and creates an excessive amount of frost. The defrost system may not be able to keep up with this extra moisture, leading to more water than the drain can handle. Check the gasket for any cracks, tears, or flattened sections.
A simple trick to test the seal is the “dollar bill test.” Close the door on a dollar bill; if you can pull the bill out with no resistance, your gasket is weak. You can often restore the shape of a flattened gasket by heating it gently with a hair dryer and then closing the door to let it “re-form” against the cabinet.
The Importance of Leveling Your Refrigerator
It might sound strange, but the level of your fridge affects how it drains. Most manufacturers recommend that the front of the refrigerator be slightly higher than the back. This ensures that the doors swing shut on their own and that water in the drain trough flows toward the back drain hole.
Use a bubble level on the top of the cabinet. If the unit is leaning forward, water might spill out of the front of the trough before it ever reaches the drain hole. Adjust the leveling legs at the front corners of the unit to give it a slight backward tilt.
Advanced Troubleshooting: Defrost Components
If you clear the drain and the ice returns within a week, you may have a failure in the defrost system components. This is less common but still a possibility for the DIY repair person to investigate. The system consists of the defrost heater, the bi-metal thermostat, and the control board.
Testing the Defrost Heater
The defrost heater is a glass or metal tube located at the bottom of the evaporator coils. If this heater burns out, the frost will never melt, eventually clogging the air passages and causing cooling issues. You can test the heater for continuity using a multimeter. If the circuit is “open,” the heater needs to be replaced.
The Bi-Metal Thermostat
The bi-metal thermostat acts as a safety switch. It tells the heater when to turn off so the freezer doesn’t get too hot. If this part fails, it may prevent the heater from turning on at all. A visible sign of failure is if the thermostat looks bulged or “blown out.” Like the heater, this can be tested with a multimeter for continuity while it is cold.
Frequently Asked Questions About Whirlpool Side by Side Refrigerator Ice in Bottom of Freezer
Why does ice keep forming even after I melt it?
If the ice returns quickly, it usually means the drain tube is still restricted further down, or the duckbill valve at the back is stuck shut. Simply melting the ice in the freezer isn’t enough; you must ensure the entire path to the drain pan is clear.
Can I use a hair dryer to melt the ice?
Yes, but you must be extremely careful. The plastic interior of the freezer can melt or warp very easily under high heat. Keep the hair dryer moving and never hold it in one spot for more than a few seconds. Using hot water is generally safer for the appliance.
How often should I clean my refrigerator drain?
For most homes, this isn’t a regular maintenance item. However, if you live in a high-humidity environment or have a model prone to clogs, checking the drain line once a year while you clean your condenser coils is a good practice.
Is this ice buildup dangerous for the refrigerator?
While a small amount of ice isn’t immediately “deadly” for the fridge, it forces the unit to run longer cycles and can eventually lead to the evaporator fan hitting the ice, which causes a loud buzzing or grinding noise and can break the fan motor.
Final Tips for a Successful DIY Repair
Fixing a whirlpool side by side refrigerator ice in bottom of freezer is one of those satisfying home maintenance tasks that makes you feel like a pro. It requires more patience than it does specialized skill. By taking the time to properly melt the ice and inspect the drain valve, you are preventing future water damage to your kitchen floors.
Remember to keep your condenser coils clean as well. When the coils under the fridge are covered in dust, the compressor runs hotter and longer, which can exacerbate moisture issues inside the unit. A quick vacuuming of the coils every six months goes a long way in extending the life of your appliance.
Don’t be intimidated by the back panel or the wires. As long as the power is off, you are just looking at a simple mechanical system. Take photos as you go so you remember exactly where each screw and plastic tab belongs. Once you hear that satisfying “gurgle” of water hitting the drain pan, you’ll know you’ve conquered the ice and saved yourself a hefty repair bill. Keep tinkering, stay safe, and enjoy your frost-free freezer!
